Cash Receipts duplicates


Hi List
We processed the same cash receipts twice in the month
of january. How to identify and fix them. We have
posted all the transactions.

It looks like the duplicate records got populated
without the check number. What is faster/easier way to
get rid of duplicates.

Thanks in advance
